This is sort of a gourmet version of the baked potato but it's quite an easy process. You end up with a potato skin so delectable that you feel compelled to eat it (which is where lots of the vitamins are.) I like to use baking-sized Russets for this recipe but you can use whatever you have. If you're baking smaller potatoes, just cut back on the time a bit. It's important that all the potatoes be about the same size to insure uniform doneness. Also, I use extra virgin olive oil because it comes from the first pressing and it's pure, not extracted by the use of chemicals as in the case of cheaper olive oils.
